Another behavioral issue is when a dog lunges aggressively, as if to bite, when he gets startled. This is very common with dogs who are not properly socialized around children or have not become comfortable with sporadic movements. There are many ways to desensitize your dog to movement. A dog who potentially lunges at what it is afraid of can be one that is unpredictable in other situations.
This can be correlated to PTSD in a military veteran who was subject to attack by the enemy. This could also be a reflex that victim of assault or abuse exemplifies. This type of reaction can be modified but not always completely corrected, according to the severity of the case.
